Abstract

La présente invention concerne des techniques qui permettent de déterminer des informations d'indicateur de qualité de canal (CQI) et d'établir des rapports concernant ces dernières. Une installation d'utilisateur (UE) peut déterminer une puissance de transmission par code de découpage en canaux, POVSF, sur la base de la puissance de transmission et d'un nombre désigné de codes de découpage en canaux, par exemple, au moyen d'une distribution uniforme de la puissance de transmission disponible entre tous les blocs de transport et la totalité des multiples codes de découpage en canaux désignés. Le UE peut estimer les SINR de plusieurs blocs de transport sur la base de POVSF, déterminer les indices CQI pour les blocs de transport sur la base des SINR et envoyer les indices CQI à un noeud B. Le noeud B peut envoyer plusieurs blocs de transport à UE sur la base des indices CQI. Le noeud B peut envoyer le ou les blocs de transport (i) avec le nombre désigné de codes de découpage en canaux au niveau de POVSF ou (ii) avec un nombre de codes de découpage en canaux au niveau de POVSF, les dimensions des blocs de transport étant établies proportionnellement aux nombres désignés et secondaires des codes de découpage en canaux.
